Improvement in lamp-extinguishers



UNITED STATES PATENT FFICE CHARLES E. ABBOTT, OF MALDEN, MASSACHUSETTS.

IMPROVEMENT IN LAMP-EXTINGUISHERS.

Specification forming part of Letters Patent No. 59,534, dated November13, 1866.

.To all whom it may concern:

Be it known that I, GHARLEs E. ABBOTT, of Malden, in the county ofMiddlesex and State of Massachusetts, have invented certain Improvementsin Extinguishers for Lamps, of which the following is a full, clear, andexact description, reference being had to the accompanying drawings,making part of this specification, in which- Figure l is a perspectiveview of a lampburner, representing my improved extinguisher closed downover the wick. Fig. 2 is a vertical section through the same, with theextinguisher lowered to uncover the wick; Fi g. 3, detail, to bereferred to hereafter.

My invention relates to that class of extinguishers for lamps for whichLettersFatent of the United States were granted to me on the 3d day ofJuly, A. D. 1866, in which the wick-tube was surrounded by asupplementary tube provided with a lid or cover, which was closed overand thrown back from the wick as the supplementary tube was raised orlowered by operating a rod carrying a toothed wheel engaging with a rackattached to the supplementary tube; and my invention consists inoperating this supplementary tube by means of a lever, instead of thetoothed wheel and rack before mentioned, thus enabling me to simplifythe construction and reduce the cost of manufacture.

To enable others skilled in the art to understand and use my invent-ion,I will proceed to .describe the manner in which I have carried it out.

In the said drawings, Arepresents the perforated casing of an ordinarykerosene-lamp burner, the cap B, which supports the chimney, beingsecured to a flat metal strip, e, which slides up and down through anaperture in the bottom of the burner in a wellknown manner.

b is the wick-tube, around which is fitted another tube, c, which slidesup and down, and is provided with a lid or cover, cl, which is hingedthereto at e, the points upon which it is hung being placed so far aboveits upper surface as to insure its falling by its own weight when thelamp is held in a vertical position.

necessary degree of friction to hold it in/ place at the required heightwhen the lid cl is closed.

A stop, g, is also formed on the tube c, to prevent the lid el frombeing thrown back too far, and this stop may have a slight spring, ifdesired, to assist iu throwing the lid down over the wick.

h is a lever, which works on a rod, l', as a fulcrum. This lever isiiattened at its outer end, as seen in Fig. 1, and at its opposite endis formed an open slot, k, Fig. 3, which may be either straight orcurved, and in this slot works a pin, l, which projects from the tube c,so that as the lever h is operated the tube will be raised or lowered toclose or open the lid rl, as required, the throw of the leyer being suchthat the tube c will be carried up sufficiently high to prevent the lidd, when closed, from striking against the top of the wick.

The lamp being lighted, and the parts being in the position representedin section in Fig. 2, when it is required to extinguish the light, it issimply necessary to place the finger on the ilattened end of the leverl1l and depress it, when the tube c will be raised until its lid l isabove the surface of the lighted wick, when the lid, being unsupportedby the side of the tube b, is free to fall by its own weight over thewick and extinguish the light, while the top of the tube c is closeddown, so that all disagreeable odors, as well as the evapo ration of theoil, are avoided; and by the employment of this extinguisher all dangerof explosion resulting from the ordinary method of extinguishing lightsby blowing them out is prevented.

When the lamp is to be lighted it is only necessary to raise the outerend of the lever h, so as to lower the tube c and uncover the wick.

Claim.

What I claim as my invention, and desire l CHARLES E. ABBOTT.
